Preparation and Enantioseparation of Biselector Chiral Stationary Phases Based on Amylose and Chitin Derivatives.
Amylose derivatives chiral stationary phases (CSPs), some of which are commercially available, are well known for their powerful enantioseparation performance. However, due to the dissolution or swelling properties of amylose derivatives, this type of CSPs prepared by coating method exhibit poor solvent tolerance and stability. In order to overcome the defect as well as maintain the chiral reco...
متن کاملReview High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases
In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...

متن کاملEnantioseparation using amylose esters as chiral stationary phases for high-performance liquid chromatography
Novel amylose ester derivatives were synthesized and their chiral recognition abilities as chiral stationary phases for highperformance liquid chromatography were evaluated. Compared with amylose benzoate derivatives, cinnamate derivatives showed a higher chiral recognition ability and some racemates could be efficiently resolved. The recognition abilities of these derivatives varied significan...
متن کاملChiral recognition mechanisms of four β-blockers by HPLC with Amylose Chiral Stationary Phase
The high performance liquid chromatography (HPLC) enantioseparation of four β-blocking agents metoprolol, bisoprolol, propranolol and atenolol was performed on amylose tris-(3,5-dimethylphenylcarbamate) chiral stationary phase using n-hexane-ethanol-diethylamine (DEA) as the mobile phase and related chiral recognition mechanisms were discussed. Enantiomeric separation of the fourβ-blockers was ...
